VA 7410 The VA 7410 has two independent back-end Fibre Channel loops to improve performance. The cabling configuration should balance the distribution of disk modules across both loops. Here are some things to remember when connecting the VA 7410 back-end cabling: - All disks in the controller enclosure are connected to loop 1. - The first disk enclosure should be connected to loop 2 to balance the disks. - Additional disk enclosures should be alternated between loops to balance the number disks on each loop. The number of disk enclosures on loop 1 should be equal to or one less than the number of enclosures on loop 2. - Do not connect a disk enclosure to both loops. Refer to Figure 14 when connecting disk enclosures to the VA 7410. 1 Determine which disk enclosures will be on loop 1 and which will be on loop 2. 2 Connect loop 1 disk enclosures as follows. a Connect a back-end fiber optic cable from the DISK 1 FC port on array controller 1 to the PORT 0 or PORT 1 FC connector on the closest disk enclosure on loop 1. b Connect a back-end fiber optic cable from the DISK 1 FC port on array controller 2 to the PORT 0 or PORT 1 FC connector on the same disk enclosure on loop 1. c Connect all loop 1 disk enclosures together by connecting fiber optic cables between the PORT 0 and PORT 1 FC connectors on the enclosures. 3 Connect loop 2 disk enclosures as follows. a Connect a back-end fiber optic cable from the DISK 2 FC port on array controller 1 to the PORT 0 or PORT 1 FC connector on the closest disk enclosure on loop 2. b Connect a back-end fiber optic cable from the DISK 2 FC port on array controller 2 to the PORT 0 or PORT 1 FC connector on the same disk enclosure on loop 2. c Connect all loop 2 disk enclosures together by connecting fiber optic cables between the PORT 0 and PORT 1 FC connectors on the enclosures.
